Daniel Libeskind is no stranger to tragedy. The Polish American architect is best known for his crystalline designs that commemorate historical trauma, from the Jewish Museums in Berlin and Copenhagen to the World Trade Center master plan in New York. His latest project, though smaller in footprint, is perhaps more complex in scope: a new 45,000-square foot complex in Pittsburgh for a new national organization dedicated to ending antisemitism, simply called Tree of Life. It was there that on October 27, 2018—during morning prayer services for Shabbat—a gunman opened fire, killing 11 people and wounding 6 others, including several Holocaust survivors. It was the first mass murder of Jews on U.S. soil, shattering a congregation, a community, and the image of America as a haven from antisemitism.
